What is the PSTN Switch Off?

Traditional telephony and broadband connectivity has been supported by a network of analogue copper lines known as the PSTN or the slightly more modern, but still outdated ISDN. This means that all solutions that still rely on PSTN/ISDN will need to move over to solutions that solely run via the internet or fibre technology. The deadline for the Switch-Off is 2025 – but it is a process that will be completed gradually, and it has already begun with the network becoming obsolete in locations around the UK.

If your business still relies on the PSTN/ISDN to power your solutions, the time to move to over to digital solutions is now to avoid your business communications, connectivity and business solutions being affected by the Switch-Off.

Why Is It Happening and What Will Replace the PSTN?

The reason the PSTN/ISDN is being shut down is because it no longer serves the needs of the modern world. We’ve moved on from only needing voice capabilities from our business phone system. We’re utilising video calls, instant messaging and other channels that the PSTN or ISDN wasn’t designed to support. We are also demanding more from our connectivity to power a range of business services such as communications, technology, security and more, which copper solutions don’t have the speeds or bandwidth to cope with. Instead, the world is moving on to digital solutions powered by full-fibre connectivity and delivering voice services over the internet.

Not only will moving to internet-based and fibre, digital solutions future-proof your business, it will provide a wealth of new features and opportunities too. From improving communications to boosting productivity, streamlining processes and providing a better experience for your customers, digital solutions have the power to take your business to the next level.

FAQs

The PSTN (Public Switched Telephone Network) and ISDN (Integrated Services Digital Network) are two networks that transfer voice and data over analogue copper lines. The PSTN is the traditional physical phone network that has been around since the 19th century. The ISDN provides digital connectivity to provide a range of services, both voice and non-voice, and was introduced in 1960, when the PSTN was unable to provide long-distance connections.

Traditional landline telephony is being phased out in favour of feature-rich, reliable and resilient VoIP telephony. Rather than calls travelling over the complex, analogue PSTN system, traffic will now be routed via your broadband connection instead. If your business still relies on traditional telephony that utilises analogue lines rather than the internet, you will need to switch over to VoIP telephony soon.

No. The 2025 deadline is just that - a deadline for the completion of the project. Work has already started in locations around the UK with businesses losing access to the PSTN. The time is now to switch to prevent disruption to your business and in order to find the best deals on new solutions for your business.

First you need to analyse which solutions within your business will need replacing before the switch off, then you will need to research which internet-based alternatives will be the best solution for your business. Engaging with a reputable and knowledgeable provider, like Elite Group, will ensure that you find the best solutions for your business at the best price. A specialist will work with you to identify your needs, before matching the right solution for those needs.

Anyone who is still relying on the PSTN and ISDN to power their solutions. Basically, if a solution is not delivered solely from an internet connection, then you will need to look at replacing that solution for an internet-based one. From telephony to broadband and infrastructure solutions, like CCTV - if it connected to the PSTN/ISDN is in any way, you will need to upgrade to an internet-based solution or risk downtime when this solution becomes obsolete during the Switch-Off.

Whether you need to move your broadband away from ADSL and onto a digital connectivity solution or you need to upgrade your phone system from a PSTN-reliant solution to a VoIP-ready solution, we're here to help. Our product suite and team of specialists provide everything you need to move away from the PSTN for good, whilst improving your business and even, potentially, saving your business money along the way.

Not necessarily. If you plan on accessing your new VoIP solution via an app, you can access it from a range of devices, including mobile phones, laptops, PCs and tablets, as well as VoIP-ready handsets. If you are still planning on utilising desk phones, then you will need to ensure that they can be connected to the internet or adapted for VoIP via an adapter. If you are not planning on using an app to access your business phone system and your handsets cannot be connected or adapted for VoIP, then you may need to consider replacing your hardware.

Making the move from the PSTN and onto digital solutions can be a daunting task. From finding the right solutions at the right price to implementing them within your business - there are a lot of hurdles that your business will have to manage. Working with the right provider can help to eliminate these hurdles as they will work with you to identify the solution you need for your business and take care of any installation and training you need to get the most out of your new digital solution.
